so i drove 6 hrs away to pick up 2 new FW rays today adn i told my little brother iw ould bring him back a kewl new fish... so i find an LFS in michigan and found scats and they dont have them where i live... and i got a peacock golby and i was told they were freshwater and could go in together in a small set up... so this is for my six yr old little brother is it ok to leave the scat freshwater if not can i just put like aquarium salt in it and if so will it be ok for the golby? and there is a kuhli loach in that tank also? grr why would you tell me they are fresh water and i come hom elook them up so i can buy what they eat and find out they are brackish..
